Patented Apr. 19, 1932 uNrrEo STATES' KARL GARLING, OF NEWARK, NEWJERSEY mnrnon ormnurncrunme rerun srr-srnaws Application filed March 12,1981. Serial No. 521,908.

Among the principal objects which the present invention has in view are:to impart a distinctive characteristic feature to the straws; toaccentuate a structural feature of the straws; to form a natural 5 iralline running throughout the complete straws; and

to simplify the method for imparting to' the product thespiral lineabove referred to.

Drawin 98 strip, the side of which has been treated to color the edge ofthe strip.

Figure 2 is a pictorial view-showing a sip-straw constructed andarranged 1n accordance with the present invention, and as resulting fromthe method herein disclosed, a portion of the paper strips composing thestraw is shown in separated relation.

a Description The present invention relates particularly to papersip-straws such as are disclosed in an application for patent filed byme under date of December 5, 1930, the serial number of which is 500,157and consists principally in preparing and employin paper stripspretreated to impart to the nished product a spiral line such asindicated by the numeral 7 in Figure 2 of the drawings. I

As disclosed, straws manufactured in accordance with the presentinvention are 'constructed of two separate strips of paper indicated inthe presentdrawings by the numerals 8 and 9. These strips are of evenwidth and are so disposed that the edges of the outer strip areapproximately disposed at the median line of the inner strip 8. The

edges of the outer strip 9 are tinted or col-' ored as indicated at 10in Figure 2. In this figure, one only tinted, but it will be understoodthat both edges may be tinted, in which case the line 7 would beintensified or broadened. "if

As shown in Figure 1, the strip 9 is tinted of the edges is shown as orcolored while rolled on the spool 11. Subsequently, this strip 9 isprovided with ad hesive 12 which causes the strip 9 to adhere to thestrip 8 when overlaid thereon.

When, now, in the process of manufacture,

the strips 8 and 9 are handled to form the sip-straw by being spirallywrapped in superosed relation on a suitable mandrel or implement, thetinted edge or edges of the strip I 9 will show throughout the length ofthe Figure 1 is a side view of a roll of paper straw as seen at the leftof Figure 2 of the drawings. YV

It will. be understood that any suitable color for tinting the edge oredges of the strip 9 may be used. Also it, will be under- 0 stood thatif desired, one edge of the said strip may have one color and theopposite edge another color, which combining in the finished product,would give varled and pleasing efiects.

Claims:

1. The method of making paper sip-straws by spirally wrapping paperstrips in superposed relation, cqloring the outermost strip prior towrapping it so that the colored por- I tion forms a visible spiral areaon the completed sip straws, and adhesively uniting said strips.

2. The method of making paper sip-straws," by spirally wrapping paperstrips in superposed relation, coloring the edge of the outer; moststrip prior to'wrapping it so that the colored edge portion forms avisible spiral line on the completed sip-straw, and adhesively unitingsaid strips.

3. The method of making paper sip-straws by spirally wrapping paperstrips in superposed relation, coloring the edge portions of theoutermost strip prior to wrapping it so i 7 that the colored' edgeportions form-visible 85 spiral areas on the completed sip-straws, andadhesively uniting said strips. 4. The method of making paper sip-strawsby spirally wrapping paper strips in super- P-Q del tion,

coloring the edges of one of said strips prior to wrapping it so thatthe colored portion forms a spiral area on the completed sip-straws, andadhesively uniting said strips.

5. The method of making paper sip-straws by spirally wrapping paperstrips in superposed relation, .coloring one edge of "said strips priorto wrapping it so that the colored portion forms a spiral area on thecompleted sip-straws, and adhesively unitin said strips.
